Abstract

The genus Aspidistra is the most diverse in southern China and northern Vietnam. We describe a new species Aspidistra xuansonensis from northern Vietnam including two varieties: A. xuansonensis var. xuansonensis with greenish white perianth and A. xuansonensis var. violiflora with purple perianth. We present DNA barcoding data of plastid psbA-trnH and nuclear 5SNTS regions for these two varieties in comparison with three other species of Aspidistra. Morphology of monopodial shoots of A. xuansonensis is described in detail. A. xuansonensis resembles recently described A. lingyunensis but differs in longer leaf petioles, longer lamina, perianth tube shape (tubular, widened at the base vs. funnel-shaped), higher anther position, and pistil shape (suddenly obconic to nearly umbrella-shaped vs. obconic gradually widened to stigma).
